Retail Price Stickiness, Market Structure and Distribution Channels

Posted by D. Daniel Sokol

Takayasu Matsuoka (Institute of Economic Research, Hitotsubashi University) analyzes Retail Price Stickiness, Market Structure and Distribution Channels.

ABSTRACT: Using Japanese scanner data of transaction prices and sales for more than 1,600 commodity groups from 1988 to 2008, we find a statistically significant negative correlation between the frequency of price changes and the degree of market concentration. We also find that structural factors of a distribution channel are significantly correlated with rigidity in retail prices. Decomposing the frequency of price changes into the frequency of intraday, sale, and regular price changes, we find that both inter- and intra-brand competition positively affect the frequency of sales. Inter-brand competition among manufacturers has a significant and positive effect on the frequency of regular price changes, whereas intra-brand competition among retailers has no such significant effect. We also document that the term of contracts between manufacturers and retailers has a significant and positive effect on price stickiness.
